\nThe correct option is B.
\n<\/section>\n
\nCommunication media carry information in various forms. Coaxial cables use electrical signals transmitted through copper wires. Microwave and satellite communication use electromagnetic waves (radio waves) transmitted through the air or space. Optic fibre cables, however, use light pulses transmitted through thin strands of glass or plastic. This method allows for very high bandwidth and long-distance transmission with minimal signal loss.
\n<\/section>\n
\nOptical fibre communication has revolutionized telecommunications and data networking due to its speed, capacity, and immunity to electromagnetic interference compared to traditional copper-based media.
